"Everything you know, all the things that you thought were important, drift into the background," Bloom, 34, said. "And even things that were important really come to the fore and he's one of them."

Saving some compliments for Flynn's mother, Bloom said it felt "wonderful" to have Miranda Kerr by his side at the premiere. "She's gorgeous," he said of his wife of nine months, who recently showed off an unbelievable post-baby body at a bikini photo shoot.

The actor also had a movie to promote, telling reporters, "I get to play a doctor who falls in love with a patient, which is a big no-no."
